What does this fault code mean?
The CEM has not received confirmation from the left rear door lock motor that the door has locked, even after a second locking command. The cause may be a defective switch that indicates the lock motor status, a lock motor stuck in the unlocked position, or a lock motor that has become too hot.
Possible causes
- Faulty status switch on the lock motor
- The lock motor has jammed in the unlocked position
- The lock motor has become too hot
What you can do
- 1Check the fault codes in the driver door and passenger door modules, as faults in the rear doors can also show there, and clear them if needed
- 2Lock and unlock the car several times with the remote control or the central locking button, and check that the door locks and unlocks
- 3Wait between locking operations, as the lock motors can become hot and stop working temporarily if used too many times in succession
- 4Check the wire to the lock unit for chafing and loose connections, and use a multimeter to check that it has no break or voltage contact
- 5If the lock unit does not work as intended and no other fault is found, it is probably internal and a workshop should replace the lock motor
Symptoms you may notice2
- Door does not lock or unlock
- Door locked or unlocked twice in succession
